Embodiment
The invention provides a kind of glass substrate water-base cleaning liquid, comprise following component (weight percent): inorganic base substance 1 ~ 5%, anion surfactant 5 ~ 15%, nonionogenic tenside 5 ~ 10%, defoamer 0.1 ~ 1%, all the other are water.
In above-mentioned water-base cleaning liquid, inorganic base substance (such as NaOH, KOH) is used for regulating PH, and scavenging solution is in the suitable PH scope all the time.Regulate clean-out system under the weak base condition, can farthest bring into play the cleaning power of clean-out system, when the inorganic alkaline component content is lower than 1wt% or is higher than 5wt%, because the product needed dilution is used, may cause pH not in suitable scope, thereby affect the decline of the cleansing power of clean-out system own, therefore, under certain condition, the ratio of inorganic base substance is determined.
Anion surfactant (take EDDHA-Na as example) not only has good chelating and dissemination, also has certain corrosion inhibition, can effectively remove the impurity such as dust, glass powder of glass baseplate surface, strengthens cleaning performance.When the EDDHA-Na component content was lower than 5wt%, chelating and dissemination weakened, and the cleaning performance of dust in impurity such as glass powder descended.When the EDDHA-Na component content was higher than 15wt%, the cleaning performance of scavenging solution can descend equally.
